Temperature reflects the momentous thermal condition of a homogenous material. Measurement of temperature normally requires close, direct contact between the material and the sensor in such a manner that the sensor responds quickly to the temperature of the material. The two type of dial thermometers manufactured by A.N Instruments are as follows:  

A.N Instruments offers a comprehensive range of Diffusion resistant, non-contaminating, all metal Pressure regulator. These are specially designed and manufactured to ensure diffusion resistance and to handle safely a wide variety of high purity gases, calibration gases, toxic and corrosive gases. The selection of a suitable pressure regulator involves many criteria including the need for preventing diffusion, compatibility of materials, pressure and flow ratings, safety requirements and so on. A.N Instruments makes two types of Regulators :Single Stage and Double Stage, made of stainless steel (SS 304, SS 316) and brass. These regulators find application wherever the integrity of gases has to be maintained. Applications include high purity gas lines, chromatographic carrier gas supplies, standard gases for calibration of analytical instruments, electronic/semi-conductor grade gases which are toxic/reactive/ corrosive.

Elastic pressure gauges indicate the relative difference between the pressure of the medium and the surrounding atmosphere. The construction is simple and robust; no additional source of energy is needed for its operation. Among the existing types of sensing/elastic elements, the most commonly used are :
